Somebody (Thanks Hendrik), just point out this is wrong as much it was
wrong before and indeed it does the multiplication due to avc type (I
really failed to see that), anyway this will gonna away with other
cleanups since basically the callback receives a pointer to beginning
of the PDU in the callback (operands):
typedef size_t (*avctp_pdu_cb) (struct avctp *session, uint8_t transaction,
uint8_t *code, uint8_t *subunit,
uint8_t *operands, size_t operand_count,
void *user_data);
